why is this bug incomplete? as far as I can see there is sufficient information to triage this...

Yes - you have to set the mtu on the lxc container interfaces to match the bridge, otherwise it drops to the lowest MTU of any attached veth.

For now I've patched the config files to set the mtu correctly - but as soon as you juju add-unit --to lxc:XX it all collapses again.

For OpenStack environments running overlay networks, setting interface MTU's on hosts is absolutely critical.
